Low Voltages; Image Intensifier Voltages - Siemens ARCOSKOP Troubleshooting Manual

3 - 2

Low voltages

•
Check the operating voltages of the ARCOSKOP according to tables 1 and 2 (Fig.1 - 4).
From test point
D1.X37 (0V)
D1.X39 (0V)

With existing "operation free" option, i.e. the control console is detachable, you must mea-
sure and check on board D40 that the voltage does not exceed 5.2 V. Should the voltage
on D40 be too high, the voltage on D42 can be reduced to 5.0 V.

Image intensifier voltages

•
Take the voltages E1 / E2 / E3 and A from the test protocol of the image intensifier and
check or adjust them at the test points of the control unit listed in Table 2.
